As the title says, I'd like for people to pick apart this build and see if there's something I missed or should do differently, more higher or lower end, and why.

HTPC will be hooked up to a 42" Olevia 242-T11 1080i LCD via onboard HDMI and used for live stream, movies, netflix, internet, webcam chat, and basic computing. Very little gaming and, if any, it will not be graphic intense. I have the xbox for games.

EDIT: I'm looking for a remote control that will do a decent job controlling both the HTPC and the TV (changing sources, channel, volume, and power is all that's needed for the tv). I'm not thinking that the Rosewill will handle what I want it to.

i do have a htpc too, a Moneual 932 case with a Corsair HX520W that is virtually silent. Your issue will be to find a case that suits your needs size-wise, while still using a good psu. Don't forget that such small cases mean stock cooling (very few HSFs for small cases), and THAT can be very noisy.
